Device and method for operating a device for continuously recovering a sulphur from an h2s-containing gas

An apparatus for continuously recovering sulfur from a 0.1 to 3.0 Vol.% H2S and further gaseous sulfur compounds such as SO2, COS and CS2 as well as sulfur-containing gas stream, comprising a reduction stage in which over a fixed-bed zone formed of a bed of a hydrogenation catalyst (5, 19), the gaseous sulfur compounds and the sulfur to H2S can be reduced, and from a selective oxidation stage in which over a fixed-bed zone formed of a bed of a selective oxidation catalyst (6, 21) H2S to sulfur is implemented, characterized by a reaction vessel (4, 14), in the direction of gas flow first section, the fixed-bed zone formed of the hydrogenation catalyst (5, 19) and in the direction of gas flow second section formed of the selective oxidation catalyst fixed-bed zone (6, 21) are arranged and between the fixed-bed zones a space (7, 22) for introducing a gaseous oxygen-containing air the required cooling medium is in the gas stream.
